This weapon deals 20% less damage than the default Revolver, making it less suitable for direct conflict. However, a successful hit will fill the Spy's Cloak meter by 15%, regardless of which cloaking device is equipped. Equipping this weapon will also increases the Spy's Cloak duration to an additional 40%. Players can therefore use the gun to charge their Cloak, alongside with the added Cloak duration in order to perform an escape or traverse a guarded area. This is especially useful when there is no metal or ammunition within close proximity.

Trivia

The main character of the book is widely considered a sociopath due to his cold nature, similar to the Spy's cold and murderous actions.

L'Etranger is French for "The Stranger", "The Outsider" or "Abroad", tying in with the Spy's mysterious nature and his origins in France.

The weapon is modeled after the Nagant M1895 revolver. However the L'Etranger, like the Revolver and Ambassador, reloads with a speedloader and flip-out cylinder, whereas the actual Nagant uses an Abadie gate and hand ejector to load one cartridge at a time. Also, the Nagant has a 7-round cylinder, as opposed to the L'Etranger's cylinder holding 6, like the Spy's other revolvers. In addition, the Nagant M1895 features an unusual feature known as a Gas-Seal feature, which is used to close the gap between cylinder and barrel, increasing the muzzle-velocity and giving the Revolver the capability to be silenced. However the L'Etranger isn't silenced and can be heard normally like any other gun.

As correct nouns in the French language require an acute accent, the upper case E in the weapon's name should be É.
